This annual survey covers all Australian registered aircraft used in the General Aviation (GA) and Regional Airline sectors of the Australian aviation industry.
The GA sector is made up of all non-scheduled flying activity in Australian-registered aircraft, other than that performed by the major domestic and international airlines. The major categories of flying are private, business, training, aerial agriculture, charter and aerial work. In addition, the sport aviation segment of GA includes operations in ultralight aircraft, gliders, hang gliders and autogyros.
The basic measure of General Aviation is flying hours. All owners of VH registered aircraft (with the exception of the Australian domestic and international airlines) are surveyed annually and asked to report hours flown by each aircraft in various categories of operation, as well as total landings per aircraft. Response to this year's collection was 75 per cent.
The survey results are merged with details from the civil aircraft register, which gives access to other information such as aircraft type, engine and fuel type, country and year of manufacture, etc.
Statistics of the sport aviation segment of GA are collected from the controlling body of each sport once or twice a year. Like the rest of GA, flying hours are the prime measure of activity.
Total hours flown by Australian VH registered aircraft in the General Aviation and Regional Airline sectors were 2 million in 2013, an increase of 5.3 per cent compared with the previous year. Activity in the General Aviation sector rose in 2013, with an increase in flying hours of 2.2 per cent to 1.7 million hours. Regional Airlines recorded an increase of 31.3 per cent in flying hours. Three flying categories showed a decrease in activity—Agriculture (down by 10.4 per cent), Charter (down by 3.2 per cent), and Private flying (down by 0.6 per cent).
Charter and Aerial Work flying made up the two largest activity categories in the General Aviation sector, representing 27.9 per cent and 23.6 per cent respectively of all General Aviation flying hours during 2013. Training hours was the third largest activity category (21.8%). Private and Business flying together represented 20.8 per cent of total General Aviation activity.
In 2013 increases in flying hours in General Aviation were recorded in Test and Ferry (14.6 per cent), Aerial Work (11.4 per cent), Training (5.0 per cent), and Business (0.3 per cent).
The number of aircraft covered by the survey increased 9.3 per cent in 2013 to 13 585. The number of fixed wing, single engine aircraft increased by 7.5 per cent to 9 076, or 66.8 per cent of all registered aircraft in the General Aviation and Regional Airline sectors. Fixed wing, multi-engine aircraft increased by 13.1 per cent to 2 053 (15.1 per cent of the total). The number of helicopters increased by 14.3 per cent to 2 077 (15.3 per cent of the total), with the number of single engine helicopters increasing by 14.2 per cent to 1 850 and the number of multi-engine helicopters increasing by 15.2 per cent to 227.
In 2013, 1 398 amateur-built aircraft accounted for 10.3 per cent of all aircraft in the General Aviation and Regional Airline fleet. This represents a 7.4 per cent increase over the number of amateur-built aircraft in 2012 (1 302 aircraft).
The Australian General Aviation and Regional Airline fleet contains many older aircraft, with the average age being 27.9 years, which is an increase compared to 2012 (27.7 years). A total of 658 thousand hours (or 32.7 per cent of all flying) were performed in aircraft under 11 years old, 388.4 thousand hours (19.3 per cent) in aircraft aged between 11 and 20 years old, 293.1 thousand hours (14.6 per cent) in aircraft between 21 and 30 years old and 670.6 thousand hours (33.4 per cent) in aircraft over 30 years old.
The average age of the Regional Airline fleet increased from 17.4 to 18.7 years between 2012 and 2013. The majority of Regional Airline flying hours are conducted by turboprop aircraft (87.8 per cent), with piston engine aircraft accounting for 2 per cent, and jet aircraft for 10.2 per cent.
